Now as we are familiar with the basic configuration o the app, one might have the curiosity how does this app work in the backend. Here’s all the information about the process which is followed by Google pay app when a transaction is initiated through the app.

How Does Money Transfer work in Google Pay App?

In this section, we will explain to you how the whole process of money transfer works in Google Pay app. As this app has made use of NFC technology and peers to peer communication we will explain to you every detail of the process. If you are afraid that your banking data will get stolen, you needn’t worry as this app is developed by a mastermind company in the field of world wide web that is Google LLC. They store our data with multiple levels of encryption which is not so easy to hack. And moreover, when you pay with this app your actual details are not shared with merchants, a process named tokenization is executed in the back-end and the tokens are generated in place of your banking details.

To transfer the money to customers, Google pay app works with the following:

  • Manufacturer of devices like smartphones which are portable
  • Various Payments Service Providers
  • Symbolic Service Providers (TSP)
  • Banks which issues cards.

So basically all these factors work together to transfer the money and process follows as:

  • The identity of the customer is checked when they add a card to the app.
  • After that, a token is stored in the device of the customer securely.
  • When the person initiates a payment transaction through his/her device the tokens are transferred to the merchants.

What are the security benefits of using Google Pay?

Tokenization of the payments offers great benefits to both users and merchants to whom payment is to be made. Some of the points regarding the security are mentioned below:

  • Device lock screens, remote wipe, and token card numbers: Users are protected from loss or theft of the portable devices which contains token information.
  • TSP and Google Pay have made their code very heavy but uses simple combinations, which is very difficult to get through, thus making integration easy for merchants
  • Reducing Trader Risk: Assertion means that customer information is less sensitive to traders who store, reducing their exposure and concerns about data breaches.

A Detailed Look into Tokenization Process

Google payments use tokenization to pay the merchants, but the question here is how does this get executed when a card is added in the app. Here’s how tokenization works:

  • A user adds his card in Google Pay App.
  • So the app requires a unique token to represent the card which would be issued by the bank.
  • Once the code is generated by the bank, the card becomes “Featured” which means it is ready for the use and has a unique id associated with it.
  • Now the card which is featured is issued a token by Google pay app and after that user is ready for making payments through this app.

How to Make a Purchase with App?

To make a purchase, the customer touches his mobile device at the terminal or chooses to pay for his mobile phone application. Google Pay responds with a customer-id and encryption code that acts as a one-time password. The card network verifies the code and matches the code with the actual card number of the customer. The bank obtained and the bank issuing the customer’s card will use current customer information and billing information for the decrypted client to complete the transaction.

What are the Points to consider?

Google Pay does not process or authorize transactions; it simply facilitates secure and fast transactions by using token cards and transferring this token card and other customer information to the networks. Traders are the registered seller and must keep their own records and keep taxes properly. Traders continue to manage orders through the existing payment processing system.

Work Flow of NFC Payments by Google Pay

As we have got the knowledge of the tokenization process, now let’s observe the workflow of the NFC payment initiated by a Google pay user.

  • Customer tokenizes card: Customer adds a card to their Google pay account. Then the mobile device stores a token which is encrypted using a single or one-time use key.
  • The trader receives a token: When a customer taps the device to initiate payment at the merchant side, the user’s device sends the following information to the merchant via NFC protocol:

– The Token

– Token Expiry Date

– Cryptogram

  • Trader Payments: The merchant uses the data from the card to process payment through the Bank. Note: You must execute the payment as a cashless transaction, either through the POS system or through the payment terminal.
  • Payment Processing: The Merchant processes the captured card information via NFC using the appropriate payment network.
  • Token Translation by TSP: The TSP verifies the cryptogram, then converts the token into the number of the actual client card.
  • The card issuing bank receives the information of the cardholder: The network sends the bank the card number of the customer, it’s expiration date which is an indication that the TSP has completed validation on behalf of the same.
  • Authorization Response Received by Network: Account level validation is completed by the bank which includes authorization checks. After that authorization response is sent to the network.
  • The Successful or Failure Notification by Terminal: After the above process is complete the network passes the response from buyer to the point of sale which finally gets back to the customer. The terminal shows the customer and the trader a message of success or failure.


Oh, that is a long process, now you know how this payment app works. But you needn’t worry about all this stuff. It’s the work of Google to make this app user-friendly and all process to be taken care of. Users can just enjoy hassle-free operations and enjoy the various offers. After all all it has made money transactions simple.
